Pull staging/IIO updates from Greg KH:
"Here is the big staging and IIO driver update for 4.18-rc1.

It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.

There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:

1007 files changed, 16828 insertions(+), 227770 deletions(-)

Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.

There was loads of work in this release cycle, primarily:

- tons of ks7010 driver cleanups

- lots of mt7621 driver fixes and cleanups

- most driver cleanups

- wilc1000 fixes and cleanups

- lots and lots of IIO driver cleanups and new additions

- debugfs cleanups for all staging drivers

- lots of other staging driver cleanups and fixes, the shortlog has
the full details.

but the big user-visable things here are the removal of 3 chunks of
code:

- ncpfs and ipx were removed on schedule, no one has cared about this
code since it moved to staging last year, and if it needs to come
back, it can be reverted.

- lustre file system is removed.

I've ranted at the lustre developers about once a year for the past
5 years, with no real forward progress at all to clean things up
and get the code into the "real" part of the kernel.

Given that the lustre developers continue to work on an external
tree and try to port those changes to the in-kernel tree every once
in a while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the time
working in their out-of-tree location and get things cleaned up
properly to get merged into the tree correctly at a later date.

Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)

All of this has been in linux-next for a while with no reported
problems"

Second set of new device support, features and cleanup for IIO in the 4.18 cycle

Usual mixture of new devices support and other stuff. A couple of
staging graduations in here and some old driver drops.

New device support
* ad5686
- Add support for AD5691R, AD5692R, AD5693 and AD5693R i2c DACs
- Add support for AD5681R, AD5682R, AD5683 and AD5683R SPI DACs

of work to move out of staging.
* ADE7754
* ADE7758
* ADE7759

Staging graduations
- ad2s1200 - good cleanup from David Veenstra.
- tsl2772 (was tsl2x7x) - Brian's quest is at an end and
staging/iio/light is no more!

1st round of IIO new device support, features and cleanup for the 4.18 cycle

A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver. The end is in sight so hopefully we'll get that one out of
staging very soon!

New device support
* AD5686
- Support AD5685R (was wrongly present as AD5685)
- Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
SPI DACs with various precisions.
- Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
- Support current sensing usings a shunt resistor.
- Support simple voltage dividers.
- support simple current sense amplifiers.
* TI dac5571
- New driver and device bindings supporting:
dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
dac5573, dac6573 and dac7573
* Meson-adc
- Support for Meson AXG with DT bindings.
* mpu6050
- Support the mpu9255 which only requires additional WHOAMI entry and
compatible string.
* st_lsm6dsx
- Support for lsm330dlc combinded accelerometer and gyro sensors with
DT bindings.
* stm32_adc
- Add support for STM32MP1 with bindings.

Staging graduations
* adis16201 after some excelent cleanup by Himanshu Jha.
* adis16029 after some excelent cleanup by Shreeya Patel.

platform_device structure.
* ad7746
- Replace opencoded byte swapped i2c calls with _swapped variants.
- White space and line break readability improvements.
- Reorder includes and variable declarations where appropriate.
* ad7791
- Changes to the AD ADC library used by this driver took in the
sampling frequency. This lead to be the wrong path being the one
tied to the resulting attribute, so it didn't work, and a warning
to be printed.
* ad7780
- Remove apparent support for sampling frequency control on devices
that don't support changing the sampling attributes.
* ade7854
- Fix a read of the wrong number of bits.
- Improve error handling on i2c read/write errors.
- Rework i2c and spi code to reduce duplication.
* adis16201 (staging)
- Improve meaning inherent in some macro names by adding units etc
where relevant.
- Adjust comments to improve detail and drop the irrelevant.
- Rename register address definitions definitions to add a _REG
postfix, clearly separating them from field definitions. Reorganize
the definitions to group register address and fields.
- Use sign_extend32 rather than open coding.
- Reverse Xmas tree ordering where appropriate and align function args.
- Remove unused headers.
- Use GENMASK where appropriate instead of open coding.
* adis16209 (staging)
- Indent field definitions to visually separate them from
register address definitions.
- Use reverse xmas tree ordering where appropriate.

- Drop some unused headers.
- Use GENMASK where appropriate.
* ad2s1200

* atlas-ph-sensor
- Use msleep instead of usleep_range where the precise value doesn't
matter and the delays are long.
* bcm150
- Drop transaction splitting as core now handles it.
* cros_ec
- Move the shared header to the include/iio/common directory.
This brings it inline with the other multiple type devices.
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* hid-sensors
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* inv_mpu6050
- Clear out a second function definition for the same function.
- Don't flush fifo when the iio buffer is full but just drop excess
data.
- Tidy up set_power_itg and ensure it is used in the right places.
- Use set_power_itg rather than opencoding it again in the i2c mux
control.
- Make sure error paths disable the power if undoing power on.
- Used managed devm_ functions during probe. Delete remove function.
- Refactor to pull raw data read out of read_raw function.
- Simplify data reading error paths.

separate hardware controls.
- Tidy up variable ordering.
- Add Brian to copyright notice given consider work on this driver.
- Take advantage of hardware support for I2C address auto increment.
- Combine individuaal enable and period attributes for the two
directions on the threshold events into a single value as the
hardware doesn't separate them.
- Move integration_time* attributes from light channel to
intensity value as they effect the intensity readings directly
and the light reading only indirectly. Hence this better
reflects reality. Also move the calibscale_available.
- Avoid returning an error in the IRQ handler.
- Hard code the reg value in _clear_interrupts as it only takes
one value in the code. Result is the function has little
purpose so opencode the two remaining i2c_smbus_write_byte
calls.

- Tidy up return path in _write_interrupt_config.
- Tidy up the ID verification code.

- Use actual device defaults for default startup settings.
- SPDX
- Add some range sanity checking to sysfs attribute writes.
- Don't provide event interfaces if the interrupt line isn't available.
- Use IIO_CONST_ATTR macro for calibscale_available as it's a constant
string.
- Fix the integration time and lux equations.
- Make device IDs explicit index values in the device_channel_config array.

iio: afe: rescale: new driver

If an ADC channel measures the midpoint of a voltage divider, the
interesting voltage is often the voltage over the full resistance.
E.g. if the full voltage is too big for the ADC to handle.
Likewise, if an ADC channel measures the voltage across a shunt
resistor, with or without amplification, the interesting value is
often the current through the resistor.

This driver solves these problems by allowing to linearly scale a channel
and/or by allowing changes to the type of the channel.
